An experimental study was performed to investigate the local characteristics of heat transfer from vertical simulated micro-chips to impinging submerged circular water jets. The effects of jet velocity, and nozzle-to-plate spacing were studied in the range of Re = 5.0 × 103 ̃ 3.6 × 104 . Heat transfer rates at the stagnation point and local heat transfer distributions were correlated. Transition from laminar to turbulent flow was observed.
